Someone mentioned the 70's? That's when me and my buddy's started going there a lot after I got my first '66 VW camper van.
Willow Creek and Jade Bob, don't know if any of you know but he had a place up in the forest above WC that looked like something straight out of the Hobbit, we used to go up and burn a few with him.
Used to pull over on the hwy next to the creek in Big sur and put out the hibachi and BBQ steaks with no hassles from anybody.
Pitched many a tent at the Plaskett Creek parking lot free with no hassles.
That Molera trail? pretty cool except I've never seen so many ticks on my board sock, stopped using that.
Surf at Sand Dollar in the Fall on high pressures - offshore glass, maybe a couple of other locs would show up.
It was like that into the mid-late 80's then started noticing the change - too many people started loving it to death.
Wife and I were up there this last March, seemed pretty mellow, but know what it was going to be like in a month or so.
I know it's a cliche, but damn I'm glad I got when I did
BTW, crowds at spots like those photos makes me want to cry too.
